## Which one, for what

### Amazon Bedrock AgentCore Code Interpreter (BB)

Good for: A team already on AWS that wants agent code to run under IAM, inside a VPC and beside S3 data, for sessions up to eight hours.

Ahead on:
- Reliability, 85 against 55
- Schema & documentation, 81 against 67
- Security & auth, 87 against 62
- Transparency & trust, 72 against 56

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install

Watch for: No pause, resume or snapshot. Session files are removed when the session ends, and persistence needs a customer-owned S3 Files or EFS mount inside a VPC

### Offscreen (B)

Good for: A coding agent working on a macOS or iOS app on the developer's own Apple silicon Mac, which needs to run UI tests, the Simulator or the built app without taking the screen.

Ahead on:
- Payments & pricing, 60 against 30

Also in its favour:
- No key needed to call it
- Open source

Watch for: First commit 11 October 2026, version 0.0.5 and labelled beta, with JSON field names that may change before 1.0

## Verdicts

**Amazon Bedrock AgentCore Code Interpreter.** Each session runs in its own microVM with 2 vCPU, 8 GB and a 10 GB disk for up to eight hours, and IAM can scope access to one interpreter. Sessions cannot be paused or resumed, and an AWS account with IAM set-up is needed before a first call.

**Offscreen.** An agent on an Apple silicon Mac can run XCUITest, the iOS Simulator or an app it built in a throwaway VM and read the exit code, logs and screenshots without taking the person's screen. The project is six days old at v0.0.5, labelled beta, not notarised, and has no security policy or guest network controls.

## Before you call either

### Amazon Bedrock AgentCore Code Interpreter

1. Start a session with `StartCodeInterpreterSession`, then pass its id in the `x-amzn-code-interpreter-session-id` header on every `InvokeCodeInterpreter` call
2. Set `sessionTimeoutSeconds` when starting. The default is 900 seconds and the maximum is eight hours, and the session ends itself at the timeout
3. Stop sessions when done. Billing runs per second while code is busy, and a session left open counts against the 1,000 concurrent-session quota
4. Use `bedrock-agentcore` 1.18.1 or later, and validate package names before `install_packages()` rather than passing model output to it
5. Retry `ThrottlingException` (429) and `InternalServerException` (500) with exponential backoff, and treat `ServiceQuotaExceededException`, returned as HTTP 402, as a quota to raise

### Offscreen

1. Read `.offscreen.toml` before running anything and use its `project` key and task names. Don't guess them
2. Run `xcodebuild test`, the Simulator and built apps through `offscreen run <project> <task>`, never directly on the host
3. Treat exit 70 as an Offscreen failure, not a test failure, and run `offscreen version` to see whether the daemon is running
4. Ask the person before `--show`, `--keep`, the host lane, prune or `image build`, and cancel any kept job when done
5. Read screenshots and `.xcresult` bundles from the directory `offscreen artifacts <job>` prints
